General Information (Electronic Control System)
Various sensors feed data from the engine to the electronic control module (ECM). The ECM processes the data. The ECM sends electronic signals to the solenoids for the fuel injector. The solenoids are energized in order to start the discharge of fuel from the fuel injection pumps. The solenoids are de-energized in order to stop the discharge of fuel from the fuel injection pumps. For a complete explanation of the fuel injection process, refer to Systems Operation, "Fuel System Operation".
